How do you reach senior citizens to tell them about your department store's sweet retiree benefits? Take out ads inside crossword puzzles, which they play endlessly—at least in Brazil. In a neat little media buy, Ogilvy bought ad space inside a crossword puzzle for department store Magazine Luiza. "Retirees are the main audience for crossword puzzles in Brazil," the case-study video points out. The audience couldn't skip the ad, because they needed the solve the clue to finish the puzzle—they even had to write down the retailer's name. It's a little harder to reach older people in the U.S., since it's tough to procure ad space in Sudoku puzzles or on the backs of protest signs demanding Obama's birth certificate.
